In addition, vegetation type could have a profound impact on root-associated methanotrophic community at both DNA and cDNA levels. These results indicate that members of the genera Methylomonas (type I) and Methylocystis (type II) can significantly contribute to aerobic methane oxidation in a eutrophic wetland.PURPOSE Reasons for delayed presentation in cancer are reported as patient or professional delays. Studies have examined patient demographic factors associated with presentation delay, but it is currently unknown why patients feel they delayed presenting. METHODS Questionnaire study of consecutive patients attending an urgent suspicion of cancer clinic at a tertiary referral centre in Glasgow over a 3-month period. RESULTS 395 patients were included. 53 (13%) patients waited 0-7 days, 164 (41%) patients 1-4 weeks, 139 (35%) 1-12 months and 31 (8%) waited longer than 12 months, before presenting. 8 (3%) did not state length of time before presentation. 123 (31%) patients were not worried about their symptoms. 5 of the 13(38%) patients diagnosed with head and neck cancer, waited up to 12 months. 5 (38%) cancer patients delayed presentation because they were not worried about symptoms. CONCLUSION Patients with head and neck cancer are not worried about their symptoms and delay their presentation, possibly contributing towards later stage diagnosis.PURPOSE E-learning provides a flexible and effective approach to learning and is increasingly used in otorhinolaryngology (ORL). We developed a national theoretical e-learning course for ORL trainees and describe our experiences with implementation as well as piloting the e-learning course. METHODS E-learning course content was developed as structured multiple choice quizzes for the European core curriculum textbook. An open-source learning management system was adapted for a
